WIND POWER SYSTEMS: Solar Plus AirTHE HYBRID SOLUTION:

In most instances, solar is utilized as a power generation medium for off grid applications. At Primus Wind Power, we are advocates for wind to be used in conjunction with solar for system redundancy, more uniform power generation, and reduced depth of discharge. AIR is a suitable complement for nearly any off-grid power system where solar is being used. It is recommended that wind represent between 10% - 50% of the power generation capacity, depending on three variables:

Wind Resource: With solar accounting for 50% or more of the power generation capacity, the wind resource analysis should be focused on solar assistance, which is during winter time months when wind is at its peak. Most regions of the United States have sufficient wintertime winds to support most off-grid power needs (see winter wind resource map below).
Solar Resource (see solar resource map below): In cloud-free locations at less than 35 degrees latitude, such as Arizona, wind will comprise a smaller percentage of total power generation (typically between 10% - 20%) since wintertime solar availability is high. Other locations such as the Great Lake region or Canada with shorter and/or cloudier wintertime months, off-grid systems should have much larger wind capacity (typically between 20% - 50%).
Load Specifics: Energy loads that are necessary in the wintertime and nighttime should have a much higher wind component. A prime example is hybrid lighting, where the load is increased in the wintertime (due to longer nights) and where energy is only needed during nighttime when wind power generation can occur and solar power generation cannot.

WIND POWER TURBINE SOLUTIONS

Why Off Grid Systems Should Include Both Solar AND Wind

Wind speeds are highest during the winter months when solar resources are at their minimum
Air density is highest in winter maximizing wind power production
Wind provides power during inclement weather when sunshine is not present
Wind provides power at night

If Wind, Why AIR?

Reliability: 5-year warranty with over 150,000 units installed globally since 1995
Up Tower Controller: Integrated controls inside the turbine regulate battery voltage
Ease of Installation: Air is wired directly to battery bank, independent of PV controller and wiring
Certifications: CSA approved to UL and CSA specifications*
Quiet Operation**

*Air 30 and Air 40
**Air 40 and Air Breeze blades are specifically designed for low sound emissions

Wiring AIR into Off Grid Solar Systems:

In the case of AIR, the wind generator is wired independently and in parallel to the PV components. The output from the turbine is wired directly to the battery terminals. This enables existing solar-only systems to be easily retrofitted with an AIR system.
